Hello, We need help. We are new to keeping chickens so we may not be doing things right with their care (both pre and post sickness) and not sure if even our vet is ever certain what's going on with them. We got 3 chickens last summer and have loved having them. We lost one in October and have never been sure what the problem was. She was absolutely fine for a while and very perky and happy. Then she started to go downhill. We thought at first it was egg bound and tried to treat that and then finally had to take her to the vet - they seemed perplexed and have a multi-person consultation and put her on baytril feeling it might be a oviduct infection. She never really improved, despite giving her the meds, extra tuna to help provide protein back and some borrowed tonic to help give her a boost during her treatment of antibiotics and within a week passed away. We were devastated but still had two. We buried her in our garden and put a deterrent over her spot to avoid being dug up by predators or found by her former companions. Our others have done well for the last couple of months. Though admittedly we did not have to care for them for about 3 weeks as we were away and put them with chicken sitters. They returned home and were fine. But of course we've had some deep snow and that kept them a bit bound to their smaller covered run and some terrible weather with horrible rain and wind (one day closed their door and locked them out of their run which then encouraged them to lay in the garden). This past week, as I have found eggs in other locations I thought that a drop in egg production for one of them was due to this new habit and with some other stormy/snowy weather believed also that some of the hiding in bushes was due to that. So I may have picked up some illnesses earlier but hadn't because there seemed to be plausible reasons for both unusual behaviours. On Wednesday, we had a bit of sun and I now noticed that one of our chickens was not coming for treats or running around like the other. We took her to the vet and it was believed to be a respiratory infection and antibiotics were given to be put in her water and she received a shot at the vet. When she came home she mainly sat in the corner and eventually went to bed. The following day, she could not barely stand and lost her balance often with walking. She has since deteriorated and doesn't eat on her own or drink (so any antibiotics getting to her I have to get into her). Losing feathers, cannot stand at all and is distressed and often breathing through her mouth. I've brought her into the house and she's in a little bathroom (no radiator on as I feared it would be too hot for her in such a small room and left the window cracked to give some fresh air).I've tried to administer antibiotics through a syringe - sometimes mixing it with some yogurt as the pure fluid often doesn't get into to her. She is not eating at all on her own so I have to hand feed her. If I get it into her mouth, she'll swallow it herself but will not actively eat on her own. I've tried to give her some feed (sometimes mixed with water so mushy), scrambled eggs (for protein), tuna to help compensate for her weakened state from being on antibiotics, and corn. I also get some grit into her to help her digestion and give her yogurt to help put some good bacteria into her gut. She is pooing but it is a bit mushy, though had a harder one this morning. She is losing feathers and is not gaining strength and is currently having very labored breathing. I don't know if I should take her off the antibiotics (we've been on them in some form since Weds) as maybe they are weakening her and not getting her appetite up? Our vet also never seems certain with what could be wrong...any chance that the diagnosis might be wrong and there could be worms? We've never wormed her but gave her pellets which should help to prevent worms (Flubenvet was difficult to get recently with dist problems). As she cannot stand on her own at all, I have to prop her up on straw so she doesn't lay on her side (though I've found her that way sometimes as she sometimes has gotten panicked and started frantically kicking her legs or has just fallen over). I understand being on their side can be bad so obviously trying to avoid it but not always unavoidable with a chicken who can't keep herself up. So other possible things? Could the bad weather recently been distressing to her or penned her up too much? Could she have gotten too close or dug around the carcass of the other buried chicken? Could their food have gotten too wet from recent rain (it is under cover but they've often thrown bits of it out of the feeder - maybe searching for tastier bits - and as it is scattered on the ground could be wet and yucky)? But other chicken is still doing fine and thriving from what we can see. Is there anything else more I can do or anything I am doing that is all wrong? I am so uncertain about her symptoms and there's soooo much information online that I am trying to give her anything that will help her get her strength back but nothing is helping and it just seems like she's getting worse not better! Her breathing is very laboured and she is mouth breathing constantly now. I don't want to lose her and could use some good advice from those with lots of years of experience with chickens. She's been a very robust chicken, big girl, big eggs - though a little stand offish so doesn't like lots of handling so I a sure having me handle her a lot isn't fun and she was panting after her visit with the vet. I am also concerned about getting more chickens - which we'll need for our lone chicken if this one goes - if we're just complete incompetents on keeping them somehow. I can't stand the suffering of animals and in most animals we do pretty well (with cats and guinea pigs) but chickens/birds are new to us and sometimes their symptoms are hidden, appear to be in many different ailment listings and a mystery to many. Please help!!!
